Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is not applicable to continuous casting machines (according to the Scope) manufactured
before the date of its publication.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
It is assumed that continuous casting machines are operated and maintained by suitably trained
personnel.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.

This document does not cover safety requirements for:
— horizontal-CCM for steel;
— auxiliary plants (auxiliary plants that are outside of the limits of the CCM);
— ladles and ladle transport;
— cranes;
— winches and hoists;
— conveyors or handling systems;
— workshop equipment (mould and segment shop, tundish workshop);
— gas burners, e.g. as a part of pre-heating stations.
This document can be used in case of modernization for the parts to be modernized.
This document is not applicable to CCM's manufactured before the date of its publication.

European foreword
This document (prEN 14753:2019) has been prepared by Technical Committee CEN/TC 322 “Equipment
for making and shaping of metals - Safety requirements”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14753:2007.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.

Introduction
This document is a type C standard as stated in EN ISO 12100:2010.
This document is not applicable to continuous casting machines (according to the Scope) manufactured
before the date of its publication.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
It is assumed that continuous casting machines are operated and maintained by suitably trained
personnel.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.

1 Scope
This document applies for plant (containing machinery and equipment) used in the process of continuous
casting of liquid steel (hereafter referred to as continuous casting machine, CCM) as defined in 3.1.
This document deals with all significant hazards, hazardous situations and events relevant to machinery
and equipment for the continuous casting of steel, when they are used as intended and under conditions
of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document specifies the safety requirements to be met during design, assembly, transport,
commissioning, operation, maintenance (as described in Clause 5) and decommissioning of the
equipment.
This document assumes that the machinery and equipment of the plant is operated and maintained by
adequately trained and competent personnel (see 7.5). Manual intervention for setting, adjustment and
maintenance is accepted as part of the intended use of the plant.
This document assumes that the machinery is used with adequate workstation lighting conforming to
EN 12464-1.
National regulations regarding lighting should be considered and could differ from requirements of
EN 12464-1.
This document applies to:
— CCM for the transformation of molten liquid steel into solid products in sections (e.g. square,
rectangular, beam blank, circular);
— CCM's from the point where overhead cranes or other transport systems deposit ladles to CCM (e.g.
in a ladle turret, ladle car or ladle stand);
— via casting process and solidification process;
— via cutting equipment;
— thru the run-out-area where the cut product is finished, collected and removed from that area.
This document does not cover safety requirements for:
— horizontal-CCM for steel;
— auxiliary plants (e.g. water treatment, refractory handling);
— ladles;
— cranes;
— winches and hoists;
— conveyors or handling systems;
— workshop equipment (mould and segment shop, tundish workshop).
It is recommended to use this standard in case of modernization for the parts to be modernized.
